!Blackhole is the most mysterious objects in the infinite universe
Black holes, the enigmatic entities of the cosmos object, continue to captivate our curiosity. It is important to dispel the misconception that every star transforms into a black hole upon reaching the end of its life cycle. Extensive research by scientists have revealed that for a star to undergo this transformation, it must possess a mass at least 20 times greater than that of our sun. These colossal supergiant stars, which explode in a cataclysmic event, collapse under their own gravitational pull, resulting in the formation of a black hole. The density of these supergiant stars approaches infinity, leading to their ultimate metamorphosis into black holes. These celestial entities possess an extraordinary gravitational force, rendering them impervious to the escape of any form of matter, including light. Scientists classify black holes into three categories based on their mass: stellar-mass, supermassive, and intermediate-mass black holes. An example of a supermassive black hole resides at the heart of our Milky Way galaxy, known as the Sagittarius A black hole. Astonishingly, its mass is estimated to be a staggering 42,970,000 times that of our Sun.
